Notes:
1. Attenuations tolerances as follows: 1, 2, 3, 4, 5, 6dB: ±0.2dB
7, 8, 9, 10dB: ±0.3dB
20, 30, 40dB: ±0.4dB
2. RFA58DD rating of 30W with chip attached to proper heatsink.
The RFAxx series of 50 ohm high frequency attenuators are available
in a variety of sizes and termination styles to suit applications for
mounting on heat sinks or normal PC board materials. High thermal conductivity aluminum nitride substrates
provide the low resistance thermal path for high power dissipation applications. The RFAxx series is available
with power dissipation to 30 watts when mounted to a heat sink. Frequency performance up to 4 GHz assures
proper operation in RF and microwave power ampliers, RF transmitters and receivers and RF power sources.
